Control of magnetism in cobalt nanoparticles by oxygen passivation
D. Srikala, V. N. Singh, A. Banerjee +2
We report on the preparation of ferromagnetic cobalt nanospheres with antiferromagnetic oxide capping layer and its implication for the variation in magnetic property. The hcp coba…
Synthesis and characterization of ferromagnetic cobalt nanospheres, nanodiscs and nanocubes
D. Srikala, V. N. Singh, A. Banerjee +2
We report the synthesis of cobalt nanoparticles with different shapes and sizes by rapid pyrolysis of cobalt carbonyl in the presence of various surfactants. The size and shape of…
Strong electron-electron correlation and weak localization in CeO_{0.9}F_{0.1}Fe_{1-x}Co_xAs
S. J. Singh, J. Prakash, S. Patnaik +1
Electron-doping of the semimetal (CeOFeAs) by either fluorine (max Tc ~ 43 K)or cobalt (max Tc ~ 11 K) leads to superconductivity. Here we show the effect of transition metal (Co)…
Possible magnetoelectric coupling in the half doped charge ordered manganite, Pr_0.5Ca_0.5MnO_3-d
A. Karmakar, S. Majumdar, A. K. Singh +2
Magnetization, magnetoresistance, and magnetodielectric measurements have been carried out on the half doped charge ordered manganite, Pr_0.5Ca_0.5MnO_3. The low temperature state…
Upper critical field, superconducting energy gaps, and Seebeck coefficient in La0.8Th0.2OFeAs
J. Prakash, S. J. Singh, S. Patnaik +1
We report the synthesis and characterization of a new electron-doped La-oxypnictide superconductor by partial substitution of lanthanum by thorium. The superconducting transition t…
Superconductivity in CeO_{1-x}F_xFeAs with upper critical field of 94 T
J. Prakash, S. J. Singh, S. Patnaik +1
We have successfully synthesized Ce based oxypnictide with fluorine doping (CeO_{1-x}F_xFeAs) by a two step solid state reaction method. Detailed XRD and EDX confirm the crystal st…
